Influence of Harmonic and DC-Bias Coupling on Transformer Energization Inrush Current in Complex Power Grids
The methodological innovation of this study is a phase-domain separation-and-recombination framework that maps harmonic voltage to prospective flux, maps controlled quasi-DC winding current to magnetic operating-point displacement, and then resolves their nonlinear interaction through a shared-yoke three-limb model. A...
